If you are replacing or reinstalling your Synology you have to delete your licenses first. If you don't delete your licenses in a current/previous installation you cannot activate them again. So resolve this, you can open a ticket at Synology to solve this problem. Please attach your license card copy and invoice to the support ticket.
Please check your internet connection with the NAS, the license key cannot be activated without an internet connection. To check if the Synology NAS is correctly configured and has access to the internet, please check for DSM upgrades. If this check fails, there might be a network misconfiguration.
Please double-check your IP address, subnet-mask and default gateway network settings.
The Synology Activation servers might be busy. Also a reboot of your Synology NAS might help. So please reboot your Synology, take a cup of coffee, double-check your entered license and try again.
Your Synology license is valid for one Synology NAS. Don't use your license on multiple Synology devices. The activation will fail and the license will be black-listed by Synology.
